HLMP-3490

LED Indication - Discrete Overview

The HLMP-3490 is a single-color yellow light-emitting diode manufactured by Broadcom Limited. It utilizes Gallium Arsenide Phosphide on Gallium Phosphide technology to emit light at a peak wavelength of 585 nm. The component features a diffused tinted dome lens with a 5 mm diameter and a total height of 6.35 mm, housed in a T-1 3/4 package for through-hole radial mounting. Electrical characteristics include a forward voltage of 2 V and a maximum forward current of 20 mA. The device provides a nominal luminous intensity of 55 mcd and operates within a temperature range of -40 °C to 100 °C.

LED Indication - Discrete Feature Summary

• Emits high-brightness yellow light via Gallium Arsenide Phosphide on Gallium Phosphide material structure
• Features a diffused tinted dome lens designed for wide viewing angles
• Compatible with standard integrated circuit logic levels due to low forward voltage requirements
• Constructed with lead-free terminals compliant with RoHS standards

LED Indication - Discrete Applications

• Panel indicators for electronic equipment
• Status signaling in industrial control systems
• Visual alerts in automotive instrumentation
• Consumer appliance status displays

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm lens type and packaging configuration. The base model HLMP-3490 typically denotes a diffused lens variant, whereas suffixes such as IR002 or MU0B1 indicate non-diffused options. Ensure the selected part matches the required optical distribution for the application. Confirm RoHS compliance status and lead-free terminal specifications during procurement validation.

LED Indication - Discrete Selection Notes

Select this component when a standard 5 mm through-hole yellow LED with diffused optics is required. The 585 nm peak wavelength ensures distinct yellow visibility. Consider the 20 mA maximum forward current limit when designing drive circuits. Verify that the T-1 3/4 package dimensions fit the mechanical constraints of the target enclosure. Evaluate thermal management needs given the 100 °C maximum operating temperature rating.

LED Indication - Discrete Part Context

The HLMP-3490 belongs to the HLMP-3 series of ultra-bright LED lamps from Broadcom. This series includes various colors and lens configurations, such as the green HLMP-3590 and red variants. These components are standardized T-1 3/4 (5 mm) LEDs widely used in general-purpose indicator applications. The series emphasizes reliability and compatibility with standard PCB mounting techniques.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other HLMP-34xx series parts with matching electrical parameters but different lens types, such as HLMP-3490-IR002 for non-diffused applications. Cross-brand replacements must match the 5 mm T-1 3/4 package, 585 nm wavelength, and 20 mA current rating. Verify pinout compatibility and forward voltage tolerance before substitution.
